Isolated tuberculous liver abscess invading the abdominal wall: report of a case.

Isolated tuberculous liver parenchymal and subcapsular abscesses are unusual,^but an abdominal wall abscess secondary to a tubercular liver abscess is extremely rare. To our knowledge, there is only one reported case of an abdominal wall abscess occurring secondary to a subcapsular liver abscess. We report the first documented case of direct invasion of the abdominal wall from an isolated tuberculous liver parenchymal abscess, diagnosed by imaging, surgical, and pathological findings. Although ultrasonography and computed tomography showed nonspecific hypoechoic and hypodense findings with peripheral contrast enhancement, T2-weighted magnetic resonance imaging (MRI) revealed a heterogeneous mass with characteristic hypointensity, suggesting the presence of free radicals produced by macrophages during active phagocytosis in tuberculosis. Although our case is extremely unusual, when hypointensity on T2-weighted MRI is seen, the possibility of tuberculosis should be considered and the results of polymerase chain reaction, culture, and histopathological diagnosis must be taken into account to avoid needless invasive surgery.

A case of dual ectopic thyroid accompanied by positive antithyroid antibodies.

Ectopic thyroid tissue is an uncommon congenital aberration that is seldom present at two different sites simultaneously. The patient was a 32-year-old woman with dual ectopic thyroid accompanied by positive antithyroid antibodies. The simultaneous occurrence of dual ectopic thyroid and positive antithyroid antibodies has been documented in only two cases: the case discussed here and one previous case. The cervical ectopic thyroid was followed up by ultrasound, which showed an increase in the size of the lesion and an internal echo texture that became slightly heterogeneous after the patient had her second child. We speculated that these changes resulted from the changes in hormone demand brought on by pregnancy and parturition.

Oral peppermint oil is a useful antispasmodic for double-contrast barium meal examination.

BACKGROUND AND AIM: Intraluminally administered peppermint oil (PO) is reportedly a safe and useful antispasmodic for gastroscopy, colonoscopy and double-contrast barium enema. The aim of this study was to examine the efficacy of oral PO for double-contrast barium meal examination (DCBM) without other antispasmodics. METHODS: Two hundred and five randomly chosen subjects (PO group) and 215 sex- and age-matched controls were enrolled. All participants underwent DCBM. The PO group was orally administered PO and a barium suspension mixture at the start of DCBM. Radiographs were blindly evaluated for spasm and overlapping with barium-filled duodenal loops (scored 0-3, indicating none to severe). The quality of barium coating of the mucosa and overall diagnostic quality (scored 0-3, indicating not acceptable to excellent) were also evaluated. RESULTS: There was no significant difference in subject acceptance between PO group and controls, and no adverse effects in either group. Scores for spasm at the esophagus, lower stomach and duodenal bulb were significantly lower in the PO than in the control group (P < 0.001). Scores for overlapping at the lower stomach and duodenal bulb were significantly lower in the PO than in the control group (P < 0.05, P < 0.01, respectively). Scores for overall diagnostic quality at the esophagus, lower stomach and duodenal bulb were significantly higher in the PO than in the control group (P < 0.001). Oral PO reduces spasm of the esophagus, lower stomach and duodenal bulb, inhibits barium flow to the distal duodenum, and improves diagnostic quality without other antispasmodics. CONCLUSIONS: Oral PO is a safe, easy to use and effective antispasmodic for DCBM.
